Pfizer secures US approval for RSV vaccine

Pfizer is also seeking approval for an RSV vaccine for use in pregnant mothers to protect their newborns and was first to gain a nod from an FDA advisory committee for such a shot earlier this month. 

The US Food and Drug Administration has approved Pfizer’s vaccine against respiratory syncytial virus, as rival GSK won authorisation for a similar immunisation less than a month ago.

Pfizer’s RSV vaccine, called Abrysvo, will now go head-to-head with GSK to convince doctors to choose their shots. The RSV space is set to become even more crowded as Moderna is working on an injection for the respiratory disease that’s based on the same messenger RNA technology powering its covid-19 vaccine.
